Acid Rain
Acid Rain INTRODUCTION: John F. Kennedy once said, The supreme reality of our time is the vulnerability of our planet. This vulnerability has never been so obvious as it is when we consider the devastating effect of acid rain. Acid rain destroys entire ecosystems and jeopardizes our health. The destructive power of this silent killer is evident to everyone who visits the Adirondack Mountains of New York State. The issue of acid rain is not just a local problem; the effect of acid rain on the e...

Investigation to see how changing the temperature of Milk changes the
Investigation to see how changing the temperature of Milk changes the speed of its coagulation after adding the enzyme rennin. I will be investigating what happens to the rate of milk coagulating when I alter the temperature. I predict that as the temperature increases, so does the rate of reaction. This is because heat energy causes more collisions between the particles in the enzyme and particles in the substrate. However, very high temperatures damage enzymes by denaturing them. An enzyme, w...

Control Of Blood Glucose
Control Of Blood Glucose Blood glucose is the primary source of energy in the human body, and is the only source of energy for the brain. The glucose is transported all over the body via the blood plasma and if there is too much present it is stored in the kidneys as glycogen (polysaccharide carbohydrate). The level of blood glucose has to be maintained by the body. Too higher levels or too lower levels will cause problems in the body. The osmotic properties of the cell will be affected, if ther...

Buffers and How They Work
Buffers and How They Work Buffers in the body help to maintain homeostasis in the blood. During exercise, the muscles use up oxygen as they convert chemical energy in glucose to mechanical energy. This oxygen comes from hemoglobin in the blood. CO2 and H+ are produced during the breakdown of glucose and are removed from the muscle through the blood. This causes chemical changes in the blood. These chemical changes cause the pH level of the blood to drop. If the pH in the body drops below 7.4, a...

Global Warming
Global Warming Every time you drive a gas or diesel powered vehicle, light a fire, use electricity, or kill a plant you are contributing to the phenomenon know as global warming. Global warming is the increase of average world temperatures as a result of what is known as the greenhouse effect. All of the previously mentioned activities release greenhouse gases into the atmosphere which act like glass in a greenhouse, allowing sunlight through to heat the earth's surface but trapping the heat as ...

Investigating the Properties of the Enzyme Catalase
Investigating the Properties of the Enzyme Catalase Introduction The discovery of enzymes occurred accidentally in the late nineteenth century. The German chemist Eduard Buchnar had been attempting to harvest fluid derived from yeast extracts, to his exasperation the fluid extracts taken kept decaying. With the knowledge sugar acts as a preservative of fruit, Buchnar introduced sugar to his liquid extracts in the hope the sugar would preserve the yeast extracts. To his astonishment the yeast flu...

Enzymes
Enzymes Enzymes are biological catalysts; they speed up metabolic reactions by lowering energy barriers without being consumed by the reaction. Proteins in quaternary structure form enzymes. The chemical structure of an enzyme is related to its specificity and catalytic activity. Induced fit, cofactors, inhibitors, and specific active sites all affect the specificity and catalytic activity of enzymes. Being a protein, enzymes are affected by changes in conditions of their environment. In an expe...

Freud
Freud Freud came to see personality as having three aspects, which work together to produce all of our complex behaviours the Id, the Ego and the Superego. All 3 components need to be well-balanced in order to have good amount of psychological energy available and to have reasonable mental health.However, the Ego has a difficult time dealing with the competing demands of the Superego and the Id. According to the psychoanalytic view, this psychological conflict is an intrinsic and pervasive part ...

Depression
Depression Depression is a disease that afflicts the human psyche in such a way that the afflicted tends to act and react abnormally toward others and themselves. Therefore it comes to no surprise to discover that adolescent depression is strongly linked to teen suicide. Adolescent suicide is now responsible for more deaths in youths aged 15 to 19 than cardiovascular disease or cancer (Blackman, 1995). Despite this increased suicide rate, depression in this age group is greatly underdiagnosed an...

Globalization
Globalization GLOBAL VISION DU JOUR SYNOPSIS: Claims that the New Economy will change EVERYTHING are vastly overstated. Every few years a book comes along that perfectly expresses the moment's conventional wisdom that says pretty much what everybody else in the chattering classes is saying, but that does it in a way that somehow manages to sound fresh and profound. Notable examples were Paul Kennedy's 1989 The Rise and Fall of the Great Powers, with its theme of imperial overstretch , of a Uni...

The Matrix
The Matrix In the movie The Matrix we may see many similarities between the society that is the Matrix and that of our own society. Though this movie is an extreme exaggeration of our situation it nonetheless lets us see how we endure these same problems of being plugged in every day and how we are fighting those who seem to have control over our lives. However, the question still remains, are we getting anywhere? And if so, is it safe for all of us to unplug at once? Could we handle it? In Th...
